After one of my first civivis left a horrible taste in my mouth I swore off of them for a while. Fastforward to this model I decided to give them another chance. I receive it and it's flawless out of the box, nearly fall shut as well as having a great detent. Easy to flip or fuller flick, nearly impossible to get to fail on a flip... I have yet to get it to fail. Cheers to civivi for a great blade and white mountain for awesome service as always!
